Description

Convenient sampler for coastal beach
Technical Field
The invention relates to a sampler, in particular to a convenient sampler for coastal beach.
Background
In the process of coastal sandy coastal dynamic landform investigation, acquisition of sandy soil samples of intertidal zones is the most important investigation means. At present, the most common collection mode is to collect soil samples on the surface layer of the beach by bare hands or small iron shovels. The disadvantage of this approach is that the acquisition mode is extremely irregular, quality is difficult to guarantee, and the acquisition personnel are vulnerable to injury. Another collection mode is to use a drilling machine to take out soil, and the method has the defects of heavy and uneconomical manipulation, poor sand viscosity and difficult sampling by the drilling machine. According to practical experience, the sandy soil sample is taken in the intertidal zone in the two modes, wherein the sandy soil sample is too extreme, the sandy soil sample is too simple and lack of standardization, and the sandy soil sample is too tedious and causes great waste and is not easy to realize. Therefore, a collector which is easy to operate and convenient to carry, but can standardize the collection form and has scientific and strict property is urgently needed to be developed.
Disclosure of Invention
The invention provides a convenient coastal beach sampler for solving the technical problems in the prior art, which can rapidly, stably and conveniently collect the sand soil sample of the intertidal zone in the coastal beach area and can save the cost.
The invention adopts the technical proposal for solving the technical problems in the prior art that: a convenient coastal beach sampler comprises a buckle, a rotary rod, a lever, a counter-force bracket and a spiral drill bit; the lever is provided with a driven end, a driving end and a fulcrum, the buckle is fixed at the design position of the rotary rod, the lower end of the rotary rod sequentially penetrates through the driven end of the lever and the center of the counter-force support from top to bottom, the spiral drill bit is fixed at the lower end of the rotary rod, the fulcrum of the lever fixedly connected with the counter-force support is arranged above the counter-force support, and when the driven end of the lever is tilted upwards, the buckle is pushed to lift the spiral drill bit.
The spiral drill bit is provided with a drill body, the shape of the drill body is a cylinder with a cone angle at the bottom, spiral blades are circumferentially arranged on the outer portion of the drill body, and spiral grooves with upward openings are formed in the spiral blades.
The height of the counterforce bracket is larger than the length of the spiral drill bit.
And pins are arranged at the bottoms of the supporting legs of the counter-force brackets.
The drill body and the rotary rod are made of hollow rust-proof rod pieces.
The upper end of the rotary rod is provided with a T-shaped handle.
The invention has the advantages and positive effects that:
firstly), a spiral drill bit is connected by a rotary rod, so that a sand sample of 20 cm to 30cm below the intertidal zone beach surface can be obtained rapidly.
And two) the height of the counterforce support is greater than the length of the spiral drill bit, so that the sampler is convenient to fix.
Thirdly), the fulcrum of the lever is fixed above the counterforce support, so that the spiral drill bit which drills into sandy soil can be easily tilted, and the resistance of the recovered drill bit is reduced.
Fourth), adopt the welding of the hollow stainless rod piece, simple structure, light, easy and simple to handle, efficient, the mobility is good, save the expense.
In conclusion, the invention has the advantages of simple structure, light weight, portability, convenient operation, high efficiency, good stability, cost saving, standard acquisition form and scientific and strict performance, and related components are organically combined by using the lever principle, and the invention is used for taking sandy soil samples in coastal beach areas. The two extreme problems of crude and nonstandard sand sampling and excessive complicated waste in the coastal area in the prior art are solved.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention;
FIG. 2 is a cross-sectional view of the auger bit of the present invention;
fig. 3 is a top view of the lever of the present invention.
In the figure: 1. a T-shaped handle; 2. a rotating rod; 3. a buckle; 4. a lever; 4-1, a fulcrum; 4-2, a driven end; 5. a reaction force bracket; 6. a helical drill; 6-1, drilling the body; 6-2, helical blades; 6-3, spiral grooves.
For a further understanding of the invention, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings in which:
referring to fig. 1 to 3, a convenient coastal beach sampler comprises a buckle 3, a rotary rod 2, a lever 4, a counter-force bracket 5 and a spiral drill bit 6; the lever 4 is provided with a driven end 4-2, a driving end and a fulcrum 4-1, the buckle 3 is fixed at the design position of the rotary rod 2, the lower end of the rotary rod 2 sequentially penetrates through the driven end 4-2 of the lever and the center of the counter-force bracket 5 from top to bottom, the screw bit 6 is fixed at the lower end of the rotary rod 2, the fulcrum 4-1 of the lever fixedly connected with the screw bit is arranged above the counter-force bracket 5, and when the driven end 4-2 of the lever is lifted up, the buckle 3 is pushed to lift the screw bit 6.
In this embodiment, in order to obtain more soil samples conveniently, the spiral drill bit 6 is provided with a drill body 6-1, the shape of the drill body 6-1 is a cylinder with a cone angle at the bottom, the outer circumference of the drill body 6-1 is surrounded by a spiral blade 6-2, and the spiral blade 6-2 is provided with a spiral groove 6-3 with an upward opening for storing the soil samples. The counter-force holder 5 has a height which is greater than the length of the auger bit 6 in order to facilitate the fixing of the sampler. In order to facilitate the insertion of the reaction bracket 5 into the sandy soil, the bottoms of the supporting legs of the reaction bracket are provided with pins. In order to reduce the weight and facilitate carrying, the drill body 6-1 and the rotary rod 2 are made of hollow rust-proof rods.
